EPF10K10ATC100-1 - FLEX 10KA FPGA, 10K Gates, 100-TQFP | Intel
MPN: EPF10K10ATC100-1 ✗ Cuối đờiEPF10K10ATC100-1 Tóm tắt
An FPGA (Field-Programmable Gate Array) is a semiconductor device containing configurable logic blocks (CLBs/LABs), programmable interconnect, and I/O cells that can be electrically reprogrammed to implement custom digital logic. The FLEX 10KA family sits in the legacy programmable-logic taxonomy as FLEX → FLEX 10K → FLEX 10KA → APEX 20K → Cyclone, walking up from embedded PLD to modern high-density FPGA. EPF10K10ATC100-1 occupies the low-density end of that hierarchy, targeting glue-logic, bus-bridging and control-plane applications rather than DSP or high-throughput datapath.
Key features include a maximum internal operating frequency of 166.67 MHz, propagation delay of approximately 0.6 ns per logic element, and 6,144 bits of embedded memory. The device is supplied from a 3.3 V core supply with 5 V-tolerant I/O, and operates over the commercial 0 °C to +70 °C range. The -1 speed grade indicates the slowest bin of the family, suitable for cost-sensitive designs.
The 10KA architecture combines a sea-of-gates logic fabric with Embedded Array Blocks (EABs) used as RAM/ROM, enabling on-chip memory without consuming general-purpose logic. Each EAB provides up to 2 Kbits of memory and can be cascaded to build wider or deeper memories. This combination of logic + memory in a single device made the FLEX 10KA a popular platform in the late 1990s for telecom, industrial control, and instrumentation front-end logic.
Typical applications include legacy telecom line-card glue logic, industrial PLC and motor-control sequencers, ISA/PCI bus bridges and protocol converters, and test & measurement front-end logic. The wide 5 V-tolerant I/O is particularly useful for interfacing to legacy 5 V buses, ASICs, and microcontrollers without external level shifters.
When designing with the EPF10K10ATC100-1, note that the device is in a legacy lifecycle state and should be sourced through authorized distributors of long-term stock or franchised brokers. PCB layout requires 4-layer board with solid ground plane for the 166 MHz internal operation; I/O drive strength is configurable in 7 steps but the device does not support LVDS - use an external translator for differential signalling.
This page synthesizes distributor pricing, lifecycle risk, pin-compatible FLEX 10KA alternatives, and practical design notes that are not consolidated in the original Altera FLEX 10KA datasheet alone.

Ứng dụng tiêu biểu
EPF10K10ATC100-1 phù hợp cho 6 Áp dụngs: Legacy Telecom Line-Card Glue Logic, Industrial PLC and Motor-Control Sequencers, ISA / PCI Bus Bridges and Protocol Converters, Test & Measurement Front-End Logic, Legacy Military / Avionics Interface Cards, Networking Router / Switch Control Plane.
Legacy Telecom Line-Card Glue Logic
The EPF10K10ATC100-1 is widely deployed as glue logic on legacy telecom line cards where it bridges bus interfaces, implements framers, and integrates protocol converters on a single 3.3 V device. The 10K gates of FLEX 10KA logic, 6,144 bits of embedded array memory, and 5 V-tolerant I/O banks allow direct interface to 5 V ASICs and TTL buses without external level translators. With 166.67 MHz maximum internal frequency and 0.6 ns propagation delay, the part comfortably handles TDM bus rates and low-speed packet-control tasks. Compared with discrete 74-series logic, the EPF10K10ATC100-1 reduces board area and BOM count while providing field-reprogrammability for last-minute logic fixes.

Industrial PLC and Motor-Control Sequencers
In industrial PLC and motor-control applications, the EPF10K10ATC100-1 implements state machines, encoder quadrature decoders, PWM timing logic, and safety interlocks. The 5 V-tolerant I/Os interface directly to 24 V-to-5 V opto-isolated industrial sensor rails, while the embedded array blocks (EABs) can be configured as small lookup tables or scratchpad RAM for control loops. The 0 to +70 °C commercial temperature range and surface-mount TQFP-100 package suit sealed industrial enclosures; the legacy 3.3 V core with 5 V I/O eliminates level shifters in mixed-voltage designs. Pin-compatible -2 and -3 speed grades support timing closure in higher-frequency motor-control loops.
Được đề xuất
ISA / PCI Bus Bridges and Protocol Converters
The EPF10K10ATC100-1 is well suited to ISA-to-PCI, PCI-to-local-bus, and proprietary protocol-conversion bridges where 66 user I/Os are sufficient for the parallel interface. The FLEX 10KA architecture supports bidirectional bus buffering, address decoding, wait-state generation, and DMA handshaking all on a single device. Embedded array memory can hold small descriptor tables or configuration registers, while the 166.67 MHz internal fabric allows bridge logic to keep pace with 33 MHz PCI bus cycles. The 5 V-tolerant I/O bank is particularly valuable when bridging a 5 V ISA bus to a 3.3 V PCI segment on the same card.

Test & Measurement Front-End Logic
Test & measurement instruments such as oscilloscopes, logic analyzers, and protocol testers historically used the EPF10K10ATC100-1 to implement trigger sequencers, timing generators, and front-end data formatters. Its 0.6 ns propagation delay and 166.67 MHz fabric allow fine-grained timing control, while the embedded array blocks provide small pattern RAM for stimulus generation. The 5 V-tolerant I/O simplifies interface to legacy 5 V probe circuitry and analog front-end ASICs. Designers retain the FLEX 10KA bitstream across product generations, simplifying long-lifecycle test equipment support.
Được đề xuất
Legacy Military / Avionics Interface Cards
Older avionics and military interface cards adopted the EPF10K10ATC100-1 because the FLEX 10KA family offers industrial temperature grades and supports MIL-STD-1553 / ARINC 429 bus glue logic in a single device. The embedded array blocks are configured as small dual-port RAMs for message buffering, while the 66 user I/Os connect directly to transceiver ASICs and discrete transceivers. Long-term support programs for avionics platforms continue to procure the EPF10K10ATC100-1 through franchised long-term-stock brokers; pin-compatible -2 and -3 speed grades allow timing-margin upgrades on the same PCB layout.
Được đề xuất
Networking Router / Switch Control Plane
Late-1990s and early-2000s routers and switches used the EPF10K10ATC100-1 on line cards and supervisor modules for bus arbitration, forwarding-engine glue logic, and management-plane protocol handling. The 10K gates are enough for table lookup engines, queue managers, and serial-console bridges, while the 5 V-tolerant I/Os talk directly to legacy 5 V PHYs and bridge ASICs. Although modern designs have migrated to Cyclone / Arria FPGAs, the EPF10K10ATC100-1 continues to be specified in long-life-cycle networking equipment where bitstream compatibility is mandatory.

Ghi chú thiết kế
The EPF10K10ATC100-1 requires a clean 3.3 V core supply (VCCINT) and a separate VCCIO supply per bank, which may be 3.3 V or 5 V depending on the I/O interface target. Bulk-decouple VCCINT with a 100 µF tantalum plus 0.1 µF ceramic per pin, and place 1 µF ceramics adjacent to every VCCIO pin. Power sequencing: VCCINT must rise before or simultaneously with VCCIO to avoid I/O latch-up; an internal POR circuit handles reset but does not replace proper sequencing. Estimated quiescent current at room temperature is around 5 mA plus dynamic current proportional to toggle rate.
Use a 4-layer PCB with a dedicated ground plane directly under the TQFP-100 footprint. Decoupling capacitors must be placed within 5 mm of each VCCINT/VCCIO pin with short, wide traces (>=0.5 mm). JTAG signals TCK, TMS, TDI, TDO should be routed with impedance-matched traces (~50 Ω) and pulled up per the FLEX 10KA JTAG specification. Leave room around the device for a 14 × 14 mm TQFP land pattern with 0.5 mm pitch; do not route signals under the package. Exposed-pad versions do not exist for FLEX 10KA TC100 - thermal dissipation is through the ground leads.
The EPF10K10ATC100-1 supports I/O standards including LVTTL, LVCMOS, 5 V TTL, and PCI per the FLEX 10KA datasheet, but does NOT support LVDS - use an external translator for any differential signalling. Drive-strength configuration (7 steps) should be tuned per output bank to balance EMI and edge-rate; slow slew rate is recommended for bus-side signals to limit ground bounce. For synchronous interfaces above 100 MHz, use the global clock tree (CLK0-CLK3) and avoid routing clocks through the general-purpose routing fabric.
Common pitfalls: (1) Do not leave MSEL0/MSEL1 floating - tie to defined logic levels to select configuration mode. (2) nCONFIG must be pulled high through a 1-10 kΩ resistor; floating nCONFIG causes unpredictable configuration. (3) CONF_DONE must be pulled high externally with a 1-10 kΩ resistor to indicate successful configuration. (4) The -1 speed grade is the slowest in the family - timing closure failures may be fixed by upgrading to -2 or -3 speed grade. (5) Confirm lead-free (RoHS) status before placing into RoHS-compliant builds; pre-2010 FLEX stock may not be Pb-free.
Thông tin tuân thủ
FLEX 10KA family was released before RoHS; pre-RoHS versions contain lead solder. The -1N suffix indicates lead-free variant. Always verify RoHS/REACH compliance per specific lot date code when sourcing obsolete inventory.
